几何与拓扑讨论班——A characterization of uniruled Kaehler manifolds

报告人：Wenhao Ou，Institute of Mathematics, Chinese Academy of Sciences时间：2025年3月3日，16:45-17:35地点：紫金港校区海纳苑2幢204室摘要：We adapt Bost's algebraicity characterization to the situation of a germ in a compact Kaehler manifold. As a consequence, we extend the algebraic integrability criteria of Campana-Paun and of Druel to foliations on compact Kaehler manifolds. As an ap...

浙大-西湖几何分析讨论班——Construction of Morse Flow Lines between Self-expanders

报告人：陈乐天（University of Tennessee, Knoxville）时间：2025年1月6日（星期一），下午4:00-5:00地点：海纳苑2幢203摘要：One of the central questions in the study of mean curvature flow (MCF) is to determine whether one can flow past singularities. For asymptotically conical singularities, self-expanders model the potential continuations of MCFs past singularities. However, due to ...

浙大-西湖几何分析讨论班——Uniqueness of Kahler-Ricci Flow Limit

报告人：张州教授（悉尼大学）时间：2024年12月26日（星期四），下午3:00-4:00地点：海纳苑2幢102摘要：we discuss the fundamental/elementary problem on the uniqueness of Kahler-Ricci flow limit. The low regularity consideration is particularly convenient. There is also motivation from more recent study on the singularity type. Accidentally, what we’ve confirmed for the finite and infi...

浙大-西湖几何分析讨论班——Quantitative geometric inequalities in $\mathbb R^n$: Power growth other than 2

报告人：张翼（中科院）时间：2024年12月17日（星期二），下午4:00-5:00地点：海纳苑2幢206摘要：In the stability of geometric inequalities, usually one gets a growth with power $2$ as a lower bound for the difference of energy. For example, a remarkable result by Fusco, Maggi, and Pratelli says that, for any set of finite perimeter $E \subset \mathbb{R}^n$ with $|E| = |B|$ and a baryc...
